p_hpss_attr_in	(input): Pointer to the HPSS attributes.
p_fsalattr_out	(input/output): Pointer to the FSAL attributes. As input, it defines the attributes that the caller wants to retrieve (by positioning flags into this structure) and the output is built considering this input (it fills the structure according to the flags it contains).
p_cred	(input) HPSS Credential.

Returns:

Major error codes:

int hpss2fsal_error ( int hpss_errorcode )

hpss2fsal_error : Convert HPSS error codes to FSAL error codes.

Parameters:

hpss_errorcode (input): The error code returned from HPSS.

Returns:: The FSAL error code associated to hpss_errorcode.

Todo:: : The EBADF error also happens when file is opened for reading, and we try writting in it. In this case, we return ERR_FSAL_NOT_OPENED, but it doesn't seems to be a correct error translation.

Warning:: AIX returns EEXIST where BSD uses ENOTEMPTY; We want ENOTEMPTY to be interpreted anyway on AIX plateforms. Thus, we explicitely write its value (87).
